Compressed Air or high pressure water cooling system?

[jsbush]

Anyone ever attempted a cooling system using compressed air? I could see use for this for my computers in the shop. Design a system that cools, cleans dust, and that works in line with your compressed air system.

You could put a temp sensor with a sylonoid valve to activate the air only when it's needed.


I was also wondering if anyone has attempted a high pressure water cooling system, somewhere along the lines of 50-60PSI? I could see a use for this for say a classroom where you water cool all your computers and run the supply lines into another room where the rads are and such. This way you'd have a silent classroom. Hmm...

The problem I see with high pressure air or liquid is the noise.
Both are not going to be silent.
Turn on the faucet in a home then go to where the water enters the house to see what I mean.

You really don't need high pressure to cool with water.
You just need a good pump if you plan to move the water over distance.

lol what psi are we talking about?

There are two reasons why you would need a high pressure for water is to make up for long runs of undersized tubing and/or too many 90 degree fittings with tight radius.

The second reason would be if you already had a chilled water plant and were tapping off its supply and return loops which can operate at 50+ psig easy.

Using high pressure air to cool is only really effective if you plan to implement a vortex tube. These can cool (and heat) really well. They require 10's of cubic feet of air delivery per minute at 100 psig or higher which would require a large (three phase powered) air compressor. Both would make a lot of noise. Even if you had an air loop available the rush of a vortex tube would be very noisy and the frequency occurs in a very sensitive region for human hearing. VT's are commonly used to provide cooling to miners' suits where air conditioning of a geothermally heated shaft would be impractical.

A few people have hooked up to city water . If you would call that high pressure. I don't but to each his own. The high pressure air thing sounds good in practice . There is one problem with it tho . water in the air . Its bad and is hard to remove all of it and it can get expensive for driers. Both ideas are bad . Rule of thumD. Never use more pressure than is required to do the job effciently.

How can someone hook up to city water? What do they do with the warm water, poor it down the drain? Seems extremely inefficient.

The high pressure for water would be for long runs and multiple computers. Either way, it's hard to determine if the idea is good or bad, but definitely wouldn't be cost affective.

As for the noise in the water pipes, as long as the proper size pipes are used, you wouldn't have this problem. The problem with the noise created at the entry point of your main in your home is due to long runs, high pressure, and small diameter pipes. Run a main that is 3/4", and then down to 1/2" for faucets and you wouldn't have this problem.

Not to mention compressed air is costly.

OK . Now I see what your saying. What your asking with high pressure water can be done very easily . If done correctly I could build for example a proper set up to cool 7 pc's

each receiving up 10 gpm flow for seperate loops in each pc. With accurate flow control my cost would be about $2500. Without accurate flow control about $1000.

I have to tell you guys this its great. Sometimes I surprise myself.

I got a friend into watercooling . He turned into a performance fruit cake. But I love the guy he is good man. Any way he was building a new house and was telling me about his heating cooling setup . You know radiant floor water heat . So I says were your computer room . He said my enterainment room . Ya that i said. He said lower level . Guy put basement 10 down into earth. I said Hay lets put copper tubing down on the dirt than the insallation on top of that than do the floor for the radiant heat. He did and the system is dead silant no fans no raditor . But a constant 55F summer time water temp.

He was so pleased with himself the dam fool forgot it was my idea. LOL. Now this was a cheap efficient chiller.

geothermal!


Dayam... i want one for the house. Not just the computer.
